[0174] [Example 2] The preferred preparation method of Polygonum cuspidatum extract
[0175] Get 220 kg of Polygonum cuspidatum medicinal material (polygonidin content is 2.55%), pulverize into coarse powder passing through a 20 mesh sieve, percolate with 60% ethanol with 14 times the weight and volume of medicinal material at a flow rate of 0.6L / kg.h, extract the ethanol under reduced pressure , concentrated to an extract with a relative density of 1.05-1.08 (at 60°C), add 6 times the weight of the medicinal materials in deionized water to dissolve, centrifuge (3000 rpm, 8 minutes / time), and the supernatant is 0.8L / kg .h flow rate through D-101 macroporous adsorption resin column (column diameter: column height=1:10, resin weight is 1.5 times of medicinal material weight), with 6 times the deionized water of D-101 resin volume with 1L / kg .h flow rate to remove impurities, then use 10% ethanol 6 times the volume of D-101 resin to remove impurities at a flow rate of 0.8L / kg.h, ...
Embodiment 3
[0176] [embodiment 3] the preparation method of preferred dosage form capsule of the present invention
[0177] Take 100 grams of Polygonum cuspidatum extract prepared by the above method, crush it through a 80-mesh sieve, add 40 g of medicinal starch, stir to mix evenly, spray 80% ethanol solution, make soft material, pass through a 40-mesh sieve for granulation, and heat at 60 ° C. Dried, divided into 1000 capsules 3 # In capsules, quality inspection, packaging, ready to go. Each capsule of this product contains polydatin (C 20 h 22 o 8 ), not less than 50mg. [Specification] 140mg / grain; [Function and Indications] Clearing away heat and detoxification, dredging collaterals and relieving pain. It is used for wind, cold, dampness and heat to invade muscles, joints, muscles and bones to block the meridians, resulting in stagnation of qi and blood and blockage of veins. Symptoms include severe pain in the limbs and joints, redness and hotness in the sore spot, swollen eyes...
